Hair drier



Patented Feb. 28, 1933 UNITED STATES PATENT OFFICE i LESLIE W. COOLEY AND DAMON R. WARD, 01 DENVER, COLORADO HAIR DRIER Application filed December 16, 1929. Serial No. 414,517.

Our invention relates to hair driers. An object of the invention is to provide an apparatus that will dry and heat air before it is drawn through a persons hair.

Another obj ect, is to provide means to chew late air past a heating element, through a perpast the heating element Figure 1 is an elevation, partly in section,

of an apparatus embodying the present invention.

Figure 2 is an end elevation, looking in the direction of the arrow A of Figure 1.

Figure 3 is a section taken on the line 33 of Figure 1. 1

Figure 4 is a diagram of present apparatus.

Referring more specifically to the drawing,

the wiring of the the reference numeral 5 designates a base for the apparatus, having feet 6. Telescoping with the base 5 is a standard 7 that is adjustable with relation to the base by means of a set screw 8. A motor housing is shown at 9. The housing encloses the motor indicated at 9 in Figure 4 A band 10 around the motor housing is bolted to one arm of a bell crank 12. The

bell crank is pivoted on a yoke 13 on the standard. The other armof the bell crank carries a segmental arm 14. The segment passes through an opening 15 in the yokeand is held in its desired positions by a set screw 16.

The motor housing has a rim 17 upon which one end of a hood 18 is slipped and thereby supported. The opposite end of the hood has an inwardly extending flange 63 and provides an open end 19for the reception of a persons head. The open end 19 has a curved recess 20 for the users neck. A strip of rubber padding 21 covers the edge of the flange 63 and the edge of the neck recess. A fabric pad 22 extends across the neck recess 20 and makes a closer fit around the users neck.

A fan 23 is connected with the motorand disposed within the hood 18. The fan is preferably of the type that creates suction and also is a blower, such, for instance, as is used in vacuum cleaners.

Spaced interiorly from the walls of the hood is a shell 24, which is fastened to the motor housing by lugs 25. The shell has an opening 26 adjacent to the opening 19 of the hood, in which the users head is placed. The opening 26 also has a recess 27 for the users neck. Between the shell and hood is a space 60 approximately the width of the flange 63, so that the flange may direct inwardly air forced through the space 60 toward the open end 19.v The outer open end of the shell 24 7 terminates short of the outer open end of the hood 18 and the inwardly extending flange 63, and forms a space between the flange and shell to accommodate a portion of the users hair and into which the air circulated by the fan 23 through the space 60 is admitted. The air entering the space is directed by the flange 63 through the hair of the user in the space and thence into the shell 24 and then through the heating chamber 56 for recirculation.

In the space 60 are two heating coils 31 and 32 supported around the shell by a series of porcelain bridges 29 mounted on a band 30 on the shell. The coils heat the adjacent interior of the shell, as well as the space 60. A 85 modified construction, however, is to make the band 30 of asbestos. Ribs 49 arranged longitudinally with respect to the shell 24 provide air channels thereon to prevent the 9G 8 back to the source. The motor 9 is wired 10,5

in parallel with the coil 31. The motor circuit may be traced from the source through the wire 39, the motor, wires 35 and 45, and through the switch 33 back to the source. The rheostat is controlled by a wire 46 in a flexible sheath 47. The wire 46 has .a loop 48 at an end within easy reach of the user.

The circuit of the coil 32 is closed. by the manual switch 41. This circuit may be traced from the source, through the switch 33, wire 43, the coil 32, wire 44, the switch 41 and wires 45 and 38 back to the source.

Partitions 50 and 51 define a heating chamber 56 within the shell, which is heated by the surrounding coils. The partition 50 is shaped similarly to the contour of the back of a persons head and has a square opening 52 and a series of holes 53 around the opening. Bars 54 prevent the hair of the user from being drawn through the opening 52 into the fan. Ribs 57 are disposed opposite each other on the lower half of the shell 24. These ribs turn the air towards the back of the users head, immediately behind his ears.

The partition 51 has a central, circular opening 55 connecting the heating compartment 56 with the fan chamber. Between the lugs 25 are openings 58 that connect the interior of the shell with the space between the shell and hood. The shell has vanes 59 adjacent the open end to hold the users head in spaced relation to the shell and also to provide air channels for directing the currents of air through the shell.

A slot 61 in the hood near the openings 58 and adjacent the fan provides a discharge outlet for moisture and moisture-laden air. The moisture-carrying air is heavier than the heated air and so finds its way through the slot 61 by reason of the centrifugal force produced by the fan.

In the operation of the apparatus, a user places his head in the open ends of the hood and shell, as shown in dotted lines in Figure 1. The operator closes the switches 33 and 41, which causes both coils to heat. The coil 32 is only used for the initial heating. As soon as the temperature has risen high enough, the operator opens the switch 41. The heat of the coil 31 is thereafter controlled by the user through the medium of the rheostat operated by the wire 46.

The fan draws air into the shell past the users head, through the openings in the partition 50, through the heating compartment 56, then blows it through the openings 58 into the space 60 between the shell and h0od, and past the heating coils to the users head. As the air reaches the end openings of the shell and hood. it is again drawn into the shell. Itwill thus be seen that the heated air circulates through the apparatus and through the users hair.

The motor is stopped by moving the switch 33 to an open position.

It is apparent that changes may be made in the construction and arrangement of parts without departing from the scope of the invention.
